The general object ofthe present invention is the provision of aregulating apparatus which will .greatly facilitate the installation 10and fitting and proper co-ordination of the speed regulating machine. v7

Another object is the provision of means for adjusting the timingrelationshipof the machine and'actuating motori means with the spinningOther'and further objects will'bepointed out or indicated hereinafter,:or obvious to of the present disclosure. g

It will. be understood that in accordance with the disclosure of theabove mentioned one skilled in the art "upon an understanding patent,provision ismade for varying the speed of the driving motor inaccordance with the movement of the ring rail of the spinning machine',such variation in speed bemgaccomplished through the medium of properlyformed cams which are operated in accordance' with the verticalmovements jof the ring rail during operation. One cam operates inaccordancewith the reciprocating movementof the ringrail which takesplace repeatedly duringjthe spinning'ofthe yarn and its winding on thesuccessive conicallayersof I the co andthe other cam is operated inaccordance with the progressive movement of the ring rail as it israised to build up the entire cop. Heretofore it has been necessary toform'the cams speciallyfor each installation,

which has required a cut-and-try procedure involving individual filingof the cams in order to give them the proper shape and size to obtainthe desired speed regulation.

' cedure in installation,

The present invention obviates the necessity of-this troublesome andexpensive proby making it possible to use cams of standard or uniformprofile and obtain the regulating eifect desired in the severalinstallations, by means of adjustable interconnecting means between thecams and the motor regulating device.

. In theaccompanying drawings formingaa part-of this speclficationisshown one form of device representing an embodiment of the invention,but it is to be understood that the same is here presented forillustrative purposes only as the invention is susceptibleof embodimentin many other forms all within the-scope of the appended-claims.

* In the drawings,

Fig; 1 isan elevational view of the ap'para tus showing the cams inoneposition;

Fig. 2 is a similarelevational view showing details showing variousstood, that the numeral'lO, designates a shaft which is rotated inaccordance with the reciprocatingv operation of the ring rail, and 11designates another, shaft which is operated in accordance with'theprogressive movement ofthe, ringraila The shaft 10 carries the cam 12and the shaft '11 carries the cam 14, the profileforms of which aredesigned with respect to the intended speed variations. The

speed control or guide lever is formed of'the portions 15 and 16, bothpivoted on the'centre 17 and have anadjustable connection by means ofset screw ries the'roller 19' which bears on the profile of the cam 1'2so that the guide'lever rocked by rotation of the cam.

On the centre 20 is lever 21 which is-con'nected at one end with theelement 22 whichoperatesthe speed varying means of the motor whichoperates the spinning frame. Pivoted to the other end of the regulatinglever 21' is the transmission link 24 which carriesat its lower end theroller 25 which'bears on the arcuate margin the fguide lever 15." Byvirtue of this con- 18, whereby their angularitymay be varied. Theportion 16 cari can vbe' pivoted the regulating" nection, it will beseen, the rocking of the V guide'lever will be e'ttectiveto rocktheregulating lever 21; The lever 26 is pivoted von the centre 27 andcarries at one end the roller '28 which rides on the profile'of the cam14.

The other 'end of-the lever 26 is pivoted to a sleeve -29 whichforms amounting for'the I elementwith'respect to said-edge,:means pro.

viding :an' operative connection between said upon" the control lever:2lmay bervaried by the adjustment ofthe screws 80 and118-Thei adjustmentof the screw 30 varies the efiective lever arm m of the guide leverbywhich-the movement ofthe roller 19 is transmitted to the link 24,regulating lever 21 and reg'ulat ing connection 22.- Theshorter m is,the

smaller will be the displacement of the .regu}- lating connection 22 andconsequently, the

less will be the-amplitude of the periodic speed variation of. the motorattendant'upon the reciprocating movement of the-r1ngra1l.

The adjustment-ofthe screw 18 is efiective to; vary the total height ofthe-speed curve, i. e.,-. the base speed of the motor, for 'a givenspinning. operation. Accordingto'the angularity of the guide lever arms15-and16', the nor-- mal position of the roller 25- will be :higher orlower, resulting in' the positioningot-the regulator connection 22 toobtain a higher'or ning machine .includingga V adaptedfo'roscill:tocontrolthespeedof' lower basic motor speed. p Y j Fig, 2 shows'therelative: position 1 of; the

parts at the point of minimum cam throw,

as distingulshed from Fig. 1 which shows,

them atthe point of maximumcam ,throw.'

In Figs. 3 and4c-are shown other-arrange ments for accomplishingadjustment ofythe? guide lever, 'wherein the adjustmentuiseacecomplished by displacement of the fulcrum In the form shown in Fig; 3the ofthelever. lever is fulcrumed on a sliding-.blockfill' which isadjustablein its mounting by,means of thescrew -18, while'in Fig.5tthe'lever is eccentrically fulcrume'don a rotatable .member 17 whichisheld in-position by the screw 34;. f

By virtue of the improved control arrangement, not onlyarethe cost andinconvenience of specially formingand filing the cams foreachinstallation obviated, but also a desir able flexibility and latitudeobtained for variation of the speedregulation as desired fordifierentconditions of operation or-zoutput.
